Chasuble

The chasuble /ˈtʃæzjʊbəl/ is the outermost liturgical vestment worn by clergy for the celebration of the Eucharist in Western-tradition Christian Churches that use full vestments, primarily in the Roman Catholic, Anglican, Lutheran, and United Methodist Church (during the Eucharist). In the Eastern Orthodox Churches and in the Eastern Rite Catholic Churches, the equivalent vestment is the phelonion.

"The vestment proper to the priest celebrant at Mass and other sacred actions directly connected with Mass is, unless otherwise indicated, the chasuble, worn over the alb and stole" (General Instruction of the Roman Missal, 337). Like the stole, it is normally of the liturgical colour of the Mass being celebrated.

Origins

The chasuble originated as a sort of conical poncho, called in Latin a "casula" or "little house," that was the common outer traveling garment in the late Roman Empire. It was simply a roughly oval piece of cloth, with a round hole in the middle through which to pass the head, that fell below the knees on all sides. It had to be gathered up on the arms to allow the arms to be used freely.
